An Investigation of Mercury Emission from FBC Systems Fired with High-Chlorine coals

摘要

Mercury is widely used in industry because of its diverse properties, which makes it an important part of industrial processes and an important ingredient in many products. However, concern over health issues has led to a 75/100 decline in industrial demand for mercury over the past 11 years. The objective of this project was to study the reduction of mercury emission from coal-fired combustors by using HCI provided by high-chlorine coals to help convert elemental mercury to oxidized mercury at relatively low temperatures (500-600 deg.C).
